Light fixture accessory connector and mounting bracket

ABSTRACT

A light fixture assembly with a bracket for attaching a light fixture accessory to a stem of the light fixture assembly, the bracket being realeasably adjustable to substantially any position along a length of the stem, the light fixture assembly also having an interface for attaching various light fixture accessories to the bracket.

FIELD OF THE INVENTION

The invention relates to a light fixture with a mounting accessory, andmore specifically to a light fixture with a detachably connectableaccessory that may be fully adjustable to a desired height relative tothe light fixture.

BACKGROUND OF THE INVENTION

Free standing lamps have been utilized in various applications for manyyears. For instance, desk lamps have be utilized to provide directionallighting for work surfaces, while floor lamps have provided both directand indirect area lighting. Both desk lamps and floor lamps areincreasingly desirable for work spaces as opposed to fixed lighting infor instance the ceiling, especially with the widespread use ofcomputers and high energy costs through out the nation.

Work space however, has become increasingly limited and expensive.Individuals have attempted to pack as much into a small work space asreasonably possible with unsatisfactory results. For instance, clutteredwork spaces leads to lower productively along with lost or missing itemsand/or work.

It is also important to maintain a clean and dignified look and feel toan office, especially if an individual is doing business with thepublic. A messy and cluttered workspace can leave a negative impressionon a potential client. With the widespread use of computers and computerperipherals, large quantities of tangled cords hanging off of workspaces(i.e. desks) and running along the floor have become the norm in manyoffices. This too adds to the overall clutter in the workspace.

Various approaches have been taken to increase working surface areas.For instance, U.S. Pat. No. 4,836,403 to Blackman teaches use of amulti-use tray that is attachable to a table leg or to a vehicle windowsill. While this multi-use tray may provide additional surface area in acar or for instance, for a kitchen table, this device is not adaptablefor use in an office environment to increase surface area on and aroundfor instance, an individual's desk.

In addition, various trays have been utilized in the medical industrysuch as U.S. Pat. No. 6,457,683 to Armstrong, Sr. and U.S. Pat. No.5,114,023 to Lavin, both of which disclose an adjustable tray forholding various medical equipment. Again however, neither of thesedevices are adaptable for use in for instance, an office environment toincrease working surface area on and around for instance, anindividual's desk.

Still further, U.S. Design Pat. No. 476,509 to Orsino et al. (“the '509patent”) discloses a lighted computer pole having shelves. This computerpole however, is adapted for use in a computer room rather than in anoffice. For instance, attachment means are provided to attach the topportion of the computer pole to the ceiling and the bottom portion tothe floor. This device is not practical for use on for instance, anindividual's desk. Still further, the '509 patent does not teach thatthe shelves are detachably removable or adjustable.

SUMMARY OF THE INVENTION

Theupward taper of walls 174, 176 serves to compress interface 118 to stem108 as light fixture accessory 116 is firmly seated thereon forming aninterference connection. In addition, the inward taper of walls 174, 176serves to hold light fixture accessory 116 firmly to bracket 112 onceseated thereon. Attachment of light fixture accessory 116 to bracket 108is a simple matter as shown in FIG. 18C. Light fixture accessory 116 ismerely slid down on top of bracket 112 such that walls 178, 180 of lightfixture accessory 116 engage with walls 174, 176 of interface 118 asillustrated in FIG. 18D. To release bracket 112 is the same procedure asdisclosed in connection with FIGS. 17A-C, one simply applies an upwardforce on light fixture accessory 116 to detach it from bracket 112,which in turn releases the inward pressure on bracket 112.

FIG. 19A is yet another embodiment of bracket 112. In this embodimentbracket 112 comprises an elastically deformable material that may be fitaround stem 108 as illustrated in FIG. 19B. Bracket 112 furthercomprises protrusions 182, 184 that include posts 186, 188 with endportions 190, 192 respectively. As illustrated in FIG. 19B, a plate 194is further provided having arcuate slots 196, 198 designed to engagewith protrusions 182, 184 respectively.

As can be seen in FIG. 19C, plate 194 is fitted onto protrusions 182,184 and is then rotated as shown to lock bracket 112 to stem 108.Arcuate slots 196, 198 spiral inward such that when plate 194 is turnedas indicated in FIG. 19C, bracket 112 is drawn inward thereby clampingto stem 108. Once plate 194 is firmly attached to bracket 112, lightfixture accessory 116 may then be attached to bracket 112 as shown inFIG. 19D. light fixture accessory 116 may comprise for instance, slots200, 202 (FIG. 20A) that can engage with plate 194.

Removal may be accomplished by lifting up of light fixture accessory 116to detach it from plate 194, and then twisting plate 194 in the reversedirection than the direction applied. This in turn releases the inwardpressure on bracket 112 such that it may again be adjusted along thelength of stem 108.

While some embodiments of bracket 112 teach use of a elasticallydeformable material or use of living hinges, it is contemplated thatboth are interchangeable with each other and either may be utilized inany of the embodiments.

FIG. 20A is still another embodiment of bracket 112 and light fixtureaccessory 116. In this embodiment, bracket 112 comprises a rear mountedbracket assembly having protrusions 204, 206 extending from a bodyportion 208 of bracket 112. Protrusions 204, 206 are designed to engagewith slots 200, 202 located in light fixture accessory 116 respectively.Also provided on bracket 112 in this embodiment is fastener 210.

Application of bracket 112 is a simple matter as illustrated in FIG.20B. Light fixture accessory 116 is abutted to stem 108 while bracket112 is slid upward along stem 108 such that protrusions 204, 206 engagewith slots 200, 202. Once protrusions 204, 206 are fully seated in slots200, 202, fastener 210 may be rotated to engage with stem 108 to firmlyhold bracket 112 to stem 108.

FIG. 21A is still another embodiment of the present invention. In thisembodiment light fixture accessory 116 is provided with elongatedattachment portion 159. Mounting element 212 is provided to attach lightfixture accessory 116 to stem 108 at a selected position. Mountingelement 212 may comprise any means for attaching elongated attachmentportion 159 to stem 108 and in one advantageous embodiment comprises forinstance, two-sided tape, Velcro or any other appropriate attachmentmeans.

Once the two-sided tape is affixed to stem 108, elongated attachmentportion 159 may then be affixed to the second side of the tape.Adjustment of light fixture accessory 116 along stem 108 may happen ifthe tape is removed as illustrated in FIG. 21B.
